The Claim

Microbial fermentation of undigested plant proteins generates short-chain fatty acids and biogenic amines such as cadaverine and putrescine, resulting in simultaneous beneficial and harmful effects on gut health that are modulated by dietary context and microbial composition.

How it works
1 study reviewed
In plain English

When gut bacteria break down plant proteins that aren't digested, they produce both compounds that support gut health and compounds that may damage it, and the net effect depends on what you eat and which bacteria are present.

See the scientific wording

Microbial fermentation of undigested plant proteins can produce both beneficial metabolites (e.g., short-chain fatty acids) and potentially harmful compounds (e.g., biogenic amines like cadaverine and putrescine), creating a dualistic impact on gut health that depends on dietary context and microbial composition.

Why this might work

When plant proteins pass through the gut undigested, bacteria break them down and make two types of chemicals at the same time: some help the gut lining stay strong and reduce inflammation, while others damage the lining and trigger harmful reactions. Which effect dominates depends on what bacteria are present and what else is eaten.

  1. Study: Interactions Between Plant Proteins and Gut Microbiota as Determinants of Intestinal Health

    When gut bacteria break down plant proteins that aren’t digested, they can make both good stuff (like fatty acids that help your gut) and bad stuff (like chemicals that might hurt your gut lining), and which ones win depends on what bacteria you have and what you eat. This study says that’s true.
